FASTENING MEANS FOR- BEATER-ROLL BAR-S.

Specification of Letters Patent.

Patented Jfily a, rare.

Application filed March 1. 1919. Serial No. 280.009.

To all whom it may concern:

Be it known that we, CLARENCE FOLSOM and LEE E. HALTEMAN, citizens of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Tmprovoments in Fastening Means for Beater- Roll Bars, of which the following is a specification.

This invention relates to new and useful improvements in fastening means for beater roll bars such as are used in paper mills. The object of the invention is to provide a device of this type which clamps or holds the bars securely in place, and which permits of their removal without the use of heat.

Referring to I the accompanying drawings; Figure 1, 1s

a sectional view of a portion of a heater roll showing our invention applied thereto; Fig. 52, is an enlarged view of the holding means as is shown in Fig: 1; Fig. 3, is a plan view of a portion of the roll as is shown in Fig. 2; Fig. i is a side elevation of Fig. 2; and Fig. 5, is. a perspective view of the holding wedge.

Throughout the specification and rawings similar reference characters indicate corresponding parts.

Referring more particularly to the drawings, 1.- represents a shaftupon which is mounted end spiders 2 and a central spider 3. The end spiders 2 are provided, in the present instance, with pockets 4 having upper flanges 5 and openings 6. The pockets l are adapted to receive the corners of bars 7 which are of the conventional shape. The pockets -l are adapted to receive wedges 8, the backs 9 of which lie against inclined sides 10' of the pockets -4. The wedges 8 are driven firmly into the pockets and hold the bars 7-'against circumferential thrust. The bars are held against radial thrust by lugs -11 on the wedges 8 and which enter openings 12 in the bars. The faces of the lugs lie parallel with the backs of the wedges which permits the wedges to be easily laced in the pockets with the lugs lying 1n the openings in the bars. After being placed in the pockets, the wedges are driven in tightly by any suitable teol. After the wedges are placed in position, the space between the bar and flange, the flange and wedge and around the lug in the. opening in the bar, is filled with babbitt 13 or other soft metal. The babbitt 13 is poured into the pocket through suitable gates -1 lin the flanges 5, and to facilitate the iiow of the metal, the wedge and lug are provided with cutaway portions l5 and 16 To prevent the metal running out of the exposed ends of the openings -l2, suitable blocks may he held in the corners spiders. en it is desired to remove the bars from the roll,*the wedges are driven out of the pockets by any suitable tool which may reach the Wedges through openings 17 in the sides of the spiders. The Babbitt metal may then be chipped out which will permit of the removal of the bars. in pouring the babbitt 13, it is to be understood that the metal does not fill the entire pocket but becomes chilled and leaves the inner end of the ocket and the opening -17 empty. While in the drawings we have shown only the end spiders provided with pockets, it is to be understood that the center spider may be similarly provided. in a beater roll as thus constructed, the bars may be easily removed without the use of heat and in a short space of time; also, a minimum amount of machining is necessary as the pockets 4' may have a foundry finish.

Having described our invention, we claim: i

l. A member having pockets therein, bars provided with openings and lying in said pockets, wedges having lugs thereon in sa d pockets and adapted to hold said bars 1n p0sition, said lugs lying in sa1d open1ngs, and a filling of soft metal in said pockets adapted to hold said wedges.

2. A member having pockets there n, bars provided with openings and lying lnsa d pockets, wedges having lugs thereon 1n sa d pockets and adapted to hold said bars 1n position, said lugs lying in said openings and the faces thereof being parallel with the backs of the wedges, and a filling of so metal'in said pockets adapted to hold said wedges.

It will be seen that,

formed by the bars and r 3. A member having pockets therein, bars being provided with openings permitting provided With Openings and lying in said access to be had to said wedges. pockets, Wedges having lugs thereon in said In testimony whereof We affix our signal0 pockets and adapted to hold said bars in tures. i

5 p osition said lugs lying in'said openings,

a filling of soft metal in said pockets adapt- CLARENCE P; FOLSOM. ed to hold said Wedges, and said member LEE'E. HALTEMAN.
